# MachTen does not support dynamic loading. If you wish to, you
# can fetch, compile, and install the dld package.
# This ought to work with the ext/DynaLoader/dl_dld.xs in the 
# perl5 package. Have fun!
# Some possible locations for dld:
# ftp-swiss.ai.mit.edu:pub/scm/dld-3.2.7.tar.gz
# prep.ai.mit.edu:/pub/gnu/jacal/dld-3.2.7.tar.gz

#  Original version was for MachTen 2.1.1.

# There seem to be some hard-to-diagnose problems under MachTen's
# malloc, so we'll use Perl's. If you have problems which Perl's
# malloc's diagnostics can't help you with, you may wish to use
# MachTen's malloc after all.

# I (Tom Phoenix) don't know how to test for locales on MachTen. (If

During Configure, you may get two "WHOA THERE" messages, for $d_setlocale
and $i_db being 'undef'. You may keep the undef value.

At the end of Configure, you will see a harmless message

Hmm...You had some extra variables I don't know about...I'll try to keep 'em.
	Propagating recommended variable dont_use_nlink

Read the File::Find documentation for more information.

It's possible that test t/lib/findbin.t will fail on some configurations
of MachTen.
